USS Celsius

From Star Trek: Theurgy Wiki

The USS Celsius was a Federation starship operated by Starfleet in the mid 24th century. In 2348 Amatras Neotin gave birth to her daughter Amikris aboard the Celsius.

(It is unknown what class of starship the USS Celsius was but from the name it is likely it was an Oberth class. So far it has not been revealed if the Celsius is still in service as of 2381.)
